Recently noticed placing boats in certain places makes them disappear into the ground, so i did a bit of experimenting and found a way to reproduce the issue.
Steps to reproduce:
Place 1 grass block, then place another grass block 1 block away (can work with any block)
Place a boat in the resultant gap
It should disappear into the ground
